Troubleshooting guidelines
As you troubleshoot your system, keep the following guidelines in mind:
•
Never remove the system's cover while the system is turned on.
•
Do not attempt to open the monitor; it is extremely dangerous.
Even if the monitor's power is disconnected, stored energy within
the monitor's components can offer a painful or harmful
experience.
•
If a peripheral such as the keyboard, mouse, drive, or printer does
not appear to work, ensure that all connections are secure.
•
If an error message displays on the screen, write it down, word for
word. You may be asked about it when calling Technical Support.
•
Only qualified personnel should open the system for maintenance.
•
If you feel you are qualified to maintain the system yourself, make
certain you are properly grounded before opening the system
chassis. See "Static Electricity Precautions" on page 2 for more
information on preventing electrostatic damage to the system.
